NHTSA Complaint #11287787 — 2015 CHEVROLET TAHOE

I PURCHASED MY VEHICLE'2015 CHEVY TAHOE LT ON JULY 1, 2019 I HAVE HAD INTERMITTENT GLITCHES IN THE ELECTRICAL SYSTEM. THE HEADLIGHTS, DASH LIGHTS, AND MYLINK TOUCHSCREEN WILL COMPLETELY BLACK OUT AND THEN COME BACK ON. HOWEVER, WHEN THIS HAPPENS THE STEERING WHEEL LOCKS UP FOR A SPLIT SECOND. THIS IS HAPPENING WHILE DRIVING, AT SPEEDS OVER 50MPH, DURING THE NIGHT AND DAY. IT WAS SUSPECTED TO BE THE ALTERNATOR OR BATTERY, AFTER REPLACING THE ALTERNATOR THERE WAS NO CHANGE IN THE BEHAVIOR. IT CONTINUES TO HAPPEN. THE SERVICE STABILITRACK WARNING WILL ALSO POP UP AFTER THE POWER IS RESTORED. THIS ISSUE IS VERY DANGEROUS AND AFTER READING DOZENS OF FORUMS IT'S CLEAR THIS IS NOT AN ISOLATED INCIDENT. THIS HAS HAPPENED OVER AND OVER AT LEAST 20 TIMES SINCE JULY 2019, RANDOMLY AND COMPLETELY UNEXPECTEDLY.
